Is it possible to have multiple PyPlot windows? Or am I limited to subplots?
Solution 1
Sure, just open a new figure:
import matplotlib.pyplot as plt
plt.plot(range(10))
plt.figure()
plt.plot(range(10), 'ro-')
plt.figure(), plt.plot(...)
plt.show() # only do this once, at the end
If you're running this in the default python interpreter, this won't work, as each figure needs to enter the gui's mainloop. If you want to run things in an interactive shell, look into IPython. If you just run this normally (i.e. put it into a file and call python filename.py
) it will work fine, though.
Solution 2
Use plt.figure()
and use a certain number so that the window is fixed:
plt.figure(200)
plt.plot(x)
plt.show()
and for another plot, use a different number:
plt.figure(300)
plt.plot(y)
plt.show()
Solution 3
The answer to your question is no. You can have as many windows as you want. Firstly, just type
plt.figure(n) #n must be a different integer for every window
for every new figure you want. Secondly, write
plt.show()
only once (!) at the end of everything you want to plot. Here is an example for two histograms:
plt.figure(1)
plt.hist(dataset1)
plt.figure(2)
plt.hist(dataset2)
plt.show()
Solution 4
You can do it with the pyplot.show
properties
Example:
plt.show(block=False)

I'm not sure how to word my question more clearly. Basically, is PyPlot limited to one instance/window? Any hack or workaround I try either causes my program to freeze or for the second pyplot window to be queued until the first one is closed.

sage over 8 yearsIt is implicit in this answer (and I missed it) that you should only call
plt.show()
one time at the end. This is discussed further at stackoverflow.com/a/2399978/527489. If you call plt.show() multiple times, then it still does the queueing that the OP mentions (blocks each window until the previous window is closed). -

Antonio over 5 yearsIf the number is not important, one can simply call
plt.figure()
without arguments, and a new figure will be assigned. See docs. Also, using multiple calls toshow()
is probably not what you really want, see stackoverflow.com/a/2399978/2436175 -
Antonio over 5 yearsThis answers misses the fact that the window number is optional (a new unique number will be assigned). See docs.

George Ogden over 3 yearsYou can also do
plt.figure(name)
if you want the window to have a name!
